Measurement of the Lifetime Difference Between B_s Mass Eigenstates
D. Acosta
We present measurements of the lifetimes and polarization amplitudes for B_s --> J/psi phi and B_d --> J/psi K*0 decays. Lifetimes of the heavy (H) and light (L) mass eigenstates i…
Towards the Event Horizon - The Vicinity of AGN at Micro-Arcsecond Resolution
T. P. Krichbaum, D. A. Graham, W. Alef +18
We summarize the present status of VLBI experiments at 3 mm (86 GHz), 2 mm (129-150 GHz) and 1.3 mm (215-230 GHz). We present and discuss a new 3 mm VLBI map of M87 (Virgo A), whic…
Comparison of Three-jet Events in Proton-Antiproton Collisions at sqrt{s}=1.8 TeV to Predictions from a Next-to-leading Order QCD Calculation
Sally Seidel
The properties of three-jet events with total transverse energy greater than 320 GeV and individual jet energy greater than 20 GeV have been analyzed and compared to absolute predi…
Interval estimation in the presence of nuisance parameters. 1. Bayesian approach
Joel Heinrich, Craig Blocker, John Conway +4
We address the common problem of calculating intervals in the presence of systematic uncertainties. We aim to investigate several approaches, but here describe just a Bayesian tech…
Millimetre-VLBI Monitoring of AGN with Sub-milliarcsecond Resolution
A. Pagels, T. P. Krichbaum, D. A. Graham +10
Global millimetre VLBI allows detailed studies of the most central jet regions of AGN with unprecedent spatial resolution of a few 100-1000 Schwartzschild radii to be made. Study o…
NG7538 IRS1 N: modeling a circumstellar maser disk
M. R. Pestalozzi, M. Elitzur, J. Conway +1
We present an edge-on Keplerian disk model to explain the main component of the 12.2 and 6.7 GHz methanol maser emission detected toward NGC7538-IRS1 N. The brightness distribution…
A thin ring model for the OH megamaser in IIIZw35
R. Parra, J. E. Conway, M. Elitzur
We present a model for the OH megamaser emission in the starburst galaxy IIIZw35. The observed diffuse and compact OH maser components in this source are explained by a single phas…
Spectral line and continuum radiation propagation in a clumpy medium
J. E. Conway, M. Elitzur, R. Parra
We discuss the propagation of spectral line and continuum radiation in a clumpy medium and give general expressions for the observed absorption or emission from a cloud population.…
A Circumstellar Disc in a High-Mass Star Forming Region
Michele R. Pestalozzi, Moshe Elitzur, John E. Conway +1
We present an edge-on Keplerian disc model to explain the main component of the 12.2 and 6.7 GHz methanol maser emission detected toward NGC7538-IRS1 N. The brightness distribution…
